BUTTON COLLET.

, Application filed June so, 1922. Serial No. 572,045.

To all whom it may concern:

Be it known that I, EMORY WARD STEARNs, a citizen of the United States, re-

siding at Rosl n, in the county of Nassau and State of ew York, have invented certain new and useful Improvements in Button C'ollets, of which the following is a specification. I

This invention relates tothe manufacture of molded rubber collets and particularly to the rubber collets of buttons of the kind extensively used in the clasps forming parts of garters and hose supporters. Such clasps commonly comprise metal loops and rubber l5 collets mounted on base plates provided with studs, posts or rivets which serve to secure the collets to the base plates. It sometimes happens that thestrain of the loops on the flanged heads of the collets unduly bends or breaksthe flanges of the collets or loosens or pulls the collets ofi of the base plates, and it is the object of my invention to so strengthen the collets that this difficulty may be corrected.

In carrying out my invention 1 embed a cloth or fabric of suitable texture in the flanged head of the collet which serves to give to it such strength as to avoid all possibility of undue bending or breaking. 3 The cloth is so embedded in the collet that it not only reinforces or strengthens it as awhole but it gives the desired strength to that part of the collet which engages the under or inner side of the flange or head 33 of the post or posts which connects the collet to the base plate, thus insuring a permanent connection between the button members.

, In 'order to manufacture the button col- Ml lets'thus reinforced I employ a sectional mold formed with a plurality of suitable recesses and provided with suitable pins or posts to give form. to a plurality of collets and I place between two mold members a .2 sheet of cloth and a sheet of unvulcanized rubber. The mold sections, the rubber, and

the cloth are placed in a press and when pressure is applied, the mold sectlons are forced towards each other, the recesses are filled, and the desired form is given to the articles. In this operation the cloth is em-- bedded in the flanged heads of the collets around the central openings therein. When this operation is completed, the sheet of collets thus formed is vulcanized. The collets are cut from the sheet by dies or other suitable devices and may be tumbled or otherwise finished.

In the accompanying drawings Figure '1 is a perspective viewof one form of rubber hose supporter button collet made in accordance with my invention.

Figure 2 is another perspective view of the same collet.

Figure 3 is a sectional view showing portions of the mold members and indicating how a sheet of cloth and a sheet of rubber are inserted between the mold sections before pressure is applied.

Figure 4 is a sectional view showing the mold sections moved towards each other and in the position they assume before the mold- 111 of the rubber takes place. v

igure 5 is a detail sectional view. on an enlarged scale showirfg the appearance of the molded article after the completion of the molding operation.

Figure 6 is a perspective view of another form of hose supporter button collet extensively used.

Figure 7 is a perspective view of the same collet looking from a diiferent angle.

Figure 8 is a detail sectional view of portions of mold members suitable for forming collets such as shown in Figures 6 and 7.

Figure 9 is a sectional detail view on an enlarged scale indicating how a collet is formed in a mold of the kind shown in Figure 8.

Figure 10 is a detail perspective view indicating how the collets when first molded are joined by a thin sheet of rubber and fabric.

Figure 11 is a perspective view with parts broken away, parts in section, and parts shown in dotted lines indicating how the rubber collet shown in Figure 1 is attached to a base plate.

Figure 12 is a similar view indicatin how the collet shown in Figures 6 and 7 is at-. cached to a base plate.

Figure 13 is an enlarged detail view indi cating how the soft rubber is forced during the molding and pressing operation thiou h the meshes of the cloth.

-n ber button collets A and B applied to base lates C and D in the usual way. The colets are of the same form as those extensively used but differ from others in having cloth a, b embedded in their flanged heads. no

igures 11 and 12 I have shown r'ub- 10:15

. recessed ate to give form to the outer per posts carr In this way the flanged portions of the heads are greatly strengthened, undue bending of the flanges when employed in connection with the loops of hose supporters, is avoided and the separation of the oollets from the posts is prevented. It will be observed by reference to Figure 13 that the rubber extends through the meshes of the cloth and binds together the material on opposite sides of the cloth.

Two forms of button oollets are illustrated. The method of manufacture is substantially the same, but the form of the molds is somewhat different.

To produce the oollets shown in Figures '1 and 2 I may employ three mold sections or members E, F and G. The section E is tion of the heads of the oollets and this section carries posts or pins 6 for producing the central openings in the oollets. The collars e? adapted to form the recesses w ich receive the heads of theriv- 'ets as indicated at R in'Figure 11.

Section F is recessed at to give form to the inner or lower part 0' the collet heads and also at f to give form to the collet The section G is formed with holes g to receive the outer ends of the pins e.

The mold sections are in practice adapted to produce several hundred oollets at one operation. To do this a sheet of cloth X and a sheet of unvulcanized rubber Y is I placed between two of the sections as indicated in Figure 3 and the mold sections are brought together and placed in a suitable press. When power is applied to .the press, the pine e are forced through the cloth and the rubber Figure 4) and then'as soon as the section is forced to its full extent toward the section E, the rubber is spread and made to fill the recesses in the manner indicated in Figure 5. It will be observed ing operation is completed, the molded colso that. in this operation the whole sheet is pressed in such manner as to fill the recesses of the mold, material being taken from the sheet between the recesses. When the presslets are connected by a relatively thin sheet of material as indicated in Figure 5.

1 In the pressing operation, the rubber is th forced through the meshes of the fabric in the manner indicated in Figure 13 and thus from,the sheet by dies or other suitable devices and may be tumbled or finished in the usual way. f' v The ob ong oollets shown in Figure 12 and alsoin Figures 6 and 7 may be produced in a similar wa but the form ofthe mold is somewhat di erent, n this case the section H carries pins it to produce holes 6' in the oollets. The section I has openings i adapted to form the shanks b 'and the lower parts of the heads of the oollets and the section J has recesses, 7' to form the heads or outer ortions of the heads. The cloth sheet 3? and the.rubber sheet Y are'placed between the sections I and J in the manner indicated in Figure 8 and when pressure is ap lied, the recesses of the mold sections wi l be filled and form given to the oollets. A sheet carrying several hundred collets may be thus formed, a section of such a" the post hole as to strengthen that part of the collet which extends under the head or" flange of'the post or posts which secures the. collet to the base plate.

While I have shown and described my invention as embodied in collets for hose su porter buttons, it will be understood that it may be applied to button oollets or button members of other forms.

I claim as my invention:

1. A rubber button member having a thick, narrow flan e and having stiflenin material imbedded in the flange and exten ing to the extreme outer edge thereof to add rigidity thereto.

2. A grabber button member having; a

thick, narrow flange and having fabric 1mbedded in the flange and extending to the extreme outer ed 'e thereof to stiffen it.

3. A rubber button member having a thick, narrow flange and havin fabric im-v t bedded in the outer edge of t e flange ,to

stiflen it with the rubber extending through the meshes of the fabric. t. A button'comp-risin abase plate carrying a headed post an a flanged rubber button member having stiffening material erein held on the base plate by the post with the stifl'ening material extending under the headed portion of the post. 1

5. A- button comprisin a base plate car, i

rying a headed post an a flanged rubber button member having fabric imbedded therein held on the base plate by the post with the fabric extending under the headed portion of the post and the rubber extendmg through the meshes of the fabric.

. n testimony whereof, I have hereunto subscribed my nam e.
